Server Description
A memory-intensive virtual server pairing a massive 336 GB RAM allocation with high-frequency single-core Intel Xeon processing power.
Memory Optimized
The Microsoft Azure FX16-4ms_v2 is a memory-optimized server from the FXmsv2 family, running on the Microsoft Hyper-V hypervisor. It features an x86_64 Intel Xeon 8573C processor with 4 dedicated vCPUs (2 physical cores) clocked at 4.2 GHz, supported by a large 260 MB L3 cache. The server is equipped with an exceptionally high memory capacity of 336.0 GB (84.0 GB per core) and has no local storage, though it is premium storage capable. Benchmarks indicate top-tier single-core performance, with a Geekbench single-core score of 2278.0 and strong single-threaded compression speeds. However, multi-core performance is limited due to the low core count. This configuration is highly suited for memory-intensive, single-threaded workloads, in-memory databases, and caching applications like Redis, where massive RAM is required without the overhead of high vCPU counts.
